Title: Molding sand for spray molding of mold
Inventor: KADOI JIYUN
IPC: B22C15/24
Filed: 1981-09-21
Abstract: PURPOSE:To obtain molding sand which retains the shape thereof without collapsing by gravity after formation of layers by spraying by mixing refractory short fibers with molding sand for spray molding contg. refractory particles, liquid binders and hardeners. CONSTITUTION:Refractory short fibers are mixed with molding materials contg. refractory particles, liquid binders and hardeners at 0.1-1% by weight of said refractory particles. Thus the deviation of sprayed molding sand layers prior to hardening is prevented even with molds of intricate shapes, more particularly, with molds having many overhung parts. Here, if the amt. of the short fibers such as asbestos, ceramics or the like to be added are below said range, the effect is insufficient and if in excess of said range, it is uneconomical and, besides there is possibility of posing problems in the strength of molds. The  binders and hardeners are not particularly limited; the materials having higher rates of hardening are more prefereable.
